20ft Prefab Container Office – Metal & Steel Frame, 1 Private Room (New)

Description

The 20ft Prefab Container Office from Big Bear Containers is a rugged, wind- and watertight steel unit engineered for secure, long-lasting performance.

This 20ft portable office container is a new, USA-manufactured unit designed for on-site, remote, and temporary workspace applications — suitable as a construction site office, emergency command center, sales office, or standalone workspace where a permanent building is not practical or available. It is a standalone unit providing a self-contained portable office footprint in a 20ft format, transportable by flatbed truck and repositionable by forklift or crane depending on the site configuration.

Important — specification not confirmed: The supplier listing for this product does not provide dimensions, floor specification, electrical installation detail, insulation specification, HVAC or heating and cooling detail, window or door configuration, or tare weight. All of these are standard buyer requirements for a portable office unit. Contact Big Bear Containers before ordering to obtain the full technical specification — including internal dimensions, electrical provisions, insulation rating, heating and cooling options, and door and window configuration — to confirm this unit meets your site and operational requirements before purchase.

Insulation, heating, cooling, and electrical hookup are listed as available options on this unit — confirm which of these are included as standard and which require specification and additional cost at time of order. For guidance on temporary structure siting and permit requirements in the USA, refer to the International Code Council building standards reference and confirm requirements with your local authority before siting.

For a more fully specified portable office option, also consider our 20ft Prefab Office Building with Mini-Split HVAC, our 20ft × 10ft Insulated Container Home & Office, or our 20ft Container Home Office — all of which carry confirmed interior specifications.

Construction & Durability

The 20ft office unit is built from factory-fresh one-trip steel — corrugated Corten panels that weather to a stable oxide layer instead of rusting through. Corner castings are forged and welded to the rails, so it can be lifted, stacked, and relocated without the frame racking out of square.

Delivery & Site Preparation

Delivery is a flat rate by region from our Sacramento yard – local, nationwide and international – and the exact rate shows at checkout. Allow about 75ft of clear, straight approach so the bed can tilt and slide the unit off. Have the drop zone marked and clear on the day — the driver sets it once, and moving it afterwards means another truck.
